Struct RateLimitDescriptor

pub struct RateLimitDescriptor {
    pub entries: Vec<Entry>,
    pub limit: Option<RateLimitOverride>,
}

A RateLimitDescriptor is a list of hierarchical entries that are used by the service to determine the final rate limit key and overall allowed limit. Here are some examples of how they might be used for the domain “envoy”.

.. code-block:: cpp

[“authenticated”: “false”], [“remote_address”: “10.0.0.1”]

What it does: Limits all unauthenticated traffic for the IP address 10.0.0.1. The configuration supplies a default limit for the remote_address key. If there is a desire to raise the limit for 10.0.0.1 or block it entirely it can be specified directly in the configuration.

.. code-block:: cpp

[“authenticated”: “false”], [“path”: “/foo/bar”]

What it does: Limits all unauthenticated traffic globally for a specific path (or prefix if configured that way in the service).

.. code-block:: cpp

[“authenticated”: “false”], [“path”: “/foo/bar”], [“remote_address”: “10.0.0.1”]

What it does: Limits unauthenticated traffic to a specific path for a specific IP address. Like (1) we can raise/block specific IP addresses if we want with an override configuration.

.. code-block:: cpp

[“authenticated”: “true”], [“client_id”: “foo”]

What it does: Limits all traffic for an authenticated client “foo”

.. code-block:: cpp

[“authenticated”: “true”], [“client_id”: “foo”], [“path”: “/foo/bar”]

What it does: Limits traffic to a specific path for an authenticated client “foo”

The idea behind the API is that (1)/(2)/(3) and (4)/(5) can be sent in 1 request if desired. This enables building complex application scenarios with a generic backend.

Optionally the descriptor can contain a limit override under a “limit” key, that specifies the number of requests per unit to use instead of the number configured in the rate limiting service.

Fields

entries: Vec<Entry>

Descriptor entries.

limit: Option<RateLimitOverride>

Optional rate limit override to supply to the ratelimit service.

Trait Implementations

impl Clone for RateLimitDescriptor

fn clone(&self) -> RateLimitDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RateLimitDescriptor

fn default() -> Self

Returns the “default value” for a type.

impl Message for RateLimitDescriptor

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl Name for RateLimitDescriptor

const NAME: &'static str = "RateLimitDescriptor"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "envoy.extensions.common.ratelimit.v3"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for RateLimitDescriptor

fn eq(&self, other: &RateLimitDescriptor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
